What a site plan architect search is asking for
Many developers who search for a site plan architect need the layout first: how many units, pads, keys or bays fit, where the buildings and drive aisles go, and whether parking and density work. That drawing is a preliminary site plan, and it is what Innowave Studio produces. Searches for a preliminary site plan architect are asking for the same drawing. The sheet carries the site disposition and layout, the buildings with their rooms and floor plans, amenities, internal roads, drive aisles, parking, pads, sites or units, and the yield counts, with a site data table for acreage, zoning, density against the cap, setbacks, parking required against provided, and the unit mix.
The studio is a site plan studio, not your architect of record, and it holds no stamp. The preliminary plan leaves out the engineering layer: sewer and water pipe design, electrical and utility engineering, grading and drainage engineering. Your architect of record seals the building design where the state requires an architect, and your engineer of record does the engineering and seals it. Both build the sealed set on the preliminary plan. Whether a project needs an architect at all is set by state statute and, often, by the local building official; the rest of this page lays out those rules. For the short versions, see do I need an architect for a site plan and who prepares a site plan.
Who prepares and seals each drawing
| Stage | Drawing | Prepared by | Seal |
|---|---|---|---|
| Site selection, capital, lender and contractor pricing | Preliminary site plan with site data table | The studio | None; the plan is preliminary |
| Pre-application and concept review | Preliminary site plan, revised to staff comments | The studio | None where the jurisdiction accepts an unsealed concept plan |
| Survey base | Boundary and topographic survey | Land surveyor | Surveyor's seal |
| Site plan approval and site permits | Engineered site plan set: grading, drainage, stormwater, utilities | Engineer of record (some states also allow an architect or landscape architect) | As the state and the jurisdiction require |
| Building permit | Construction documents for the building | Architect of record, or an engineer within the state's limits | Architect's or engineer's seal above the state's line |
The jurisdictions that write down their acceptance of an unsealed concept plan are collected in where unsealed site plans are accepted.
The discipline lines are written into state law. In Alaska, architects seal building design, professional engineers seal engineered systems including civil and site work, and land surveyors seal boundary surveys and plats; no registrant may seal work outside that registration (12 AAC 36.185) [8]. Massachusetts reserves property lines to the surveyor: "the delineation of existing or proposed structures, features or Boundaries relative to property lines requires the determination of property lines and therefore must be performed by a Professional Land Surveyor" (250 CMR 5.01) [9]. New Jersey divides the site plan set by regulation: the locations of drives, parking layout, pedestrian circulation and means of ingress and egress may be prepared by "an architect, planner, engineer, or licensed landscape architect" (N.J.A.C. 13:40-7.3), the boundary and topographic survey belongs to the land surveyor, and a plan set is not approvable until the engineering sheets carry a New Jersey Professional Engineer's seal [10].
When the building needs an architect or engineer
The seal on the building is where states differ most. Each line below is the statute's or the board rule's own test; local codes can add to it.
| State | The statutory line | Source |
|---|---|---|

The site plan sheet: state and local seal rules
Separate from the building, some states and many jurisdictions say who seals the site plan itself.
- Illinois. If a site plan shows technical information such as dimensions or bearings relating to boundaries, it must be signed and sealed by a professional land surveyor as well as the design professional responsible for the proposed conditions, including where a boundary survey is used as an underlay [1].
- Iowa. "Site/Plot plans may be sealed and certified by an Iowa licensed architect, professional engineer or landscape architect" [6]. Cedar Rapids narrows that: both the Administrative and the Preliminary Site Development Plan must be "certified by a registered civil engineer licensed in the State of Iowa" [33].
- Maryland. Howard County's Site Development Plan process requires a Maryland registered engineer or architect to prepare the plans and supplemental documents [34].
- Delaware. Sussex County's code requires site plans to show the seal and signature of a registered Delaware land surveyor or professional engineer, at not more than 100 feet to one inch, on sheets no larger than 24x36 inches [35].
- Georgia. Columbia County requires all design professionals to seal plans when the building is multi-story, single-story over 5,000 sq ft, or an educational, institutional or assembly occupancy [36].
- West Virginia. Charleston requires the signature and seal of a West Virginia registered architect or engineer on plans for commercial projects over $50,000 [37].
- Washington. The Attorney General found "no bright line rule for distinguishing between design documents that must be completed by an architect and those that must be completed by an engineer," and that it is "primarily up to local building officials to determine which types of documents are required or sufficient" [29]. The board rule separates final documents, which carry the seal, signature and date, from preliminary documents, which a licensee stamps but need not sign or date (WAC 196-23-020) [38].
- Arizona. A registrant seals before submitting to "any regulatory or review body," "unless the document is marked 'preliminary,' 'draft,' or 'not for construction'" (A.A.C. R4-30-304(D)); a sealed set carries the seal and signature on each drawing sheet (R4-30-304(A)) [39].
- Kansas. Architecture covers the design of non-exempt buildings "and the spaces within and the site surrounding such buildings" (K.S.A. 74-7003) [40], and a licensee may not seal documents outside the licensee's field of practice (K.A.R. 66-6-4(d)) [41].
- Missouri. Licensees "affix the seal to all final technical submissions," a class that includes drawings, plats and exhibits, and "Nothing in this section... shall require any professional to seal preliminary or incomplete documents" (RSMo 327.411) [42]. The Metropolitan St. Louis Sewer District starts project review with "One set of plans prepared and sealed by an engineer registered in the State of Missouri" [43].
- North Carolina. The engineering act "shall not prevent ... (1) The practice of architecture as defined in Chapter 83A of the General Statutes, landscape architecture as defined in Chapter 89A of the General Statutes, or contracting" (G.S. 89C-25) [44]. Gaston County encourages, but does not require, a site plan prepared by a North Carolina licensed engineer, architect, landscape architect or land surveyor (UDO 5.2.1(A)) [45]. NCDOT Division 10's driveway package requires traffic impact analyses and drainage studies sealed by a North Carolina licensed professional [46].
- Utah. The Landscape Architects Licensing Act defines the practice to include production of a site plan (58-53-102(3)) [47], exempts persons licensed under the architects act among others (58-53-304) [48], and requires a site plan prepared in Utah to bear a landscape architect's seal unless one of those exemptions or the engineer, surveyor and architect acts applies (58-53-602) [49].
What the architect of record adds
The architect of record turns the program on the preliminary plan into the building: floor plans, elevations and building layout sheets, which in New Jersey are the architect's to seal (N.J.A.C. 13:27) [10]. Above Wisconsin's 50,000 cubic feet, the obligation runs into construction: supervising professionals file compliance statements with DSPS and the local code officials before occupancy (SPS 361.40(4)) [50]. In Illinois, the cover sheet lists the project, the design firm and its registration number, the codes used, a drawing index and the seals, with an indication of which drawings each seal covers [1].
What the architect cannot do is seal a drawing someone else finished. Illinois holds that merely reviewing, or reviewing and correcting, technical submissions prepared by others is not responsible control [1]. Wisconsin bars a registrant from impressing a seal on documents not prepared by the registrant or under the registrant's direction and control (Wis. Stat. 443.17(1)) [51]. Maryland defines approval for sealing as direct knowledge and responsible control over the content of technical submissions during their preparation (COMAR 09.21.02.03) [52]. So the preliminary plan is not a drawing for an architect to stamp. It is the program, the layout and the numbers the architect of record develops into the sealed set, under the architect's own control.
Why developers bring a preliminary site plan to the architect
The preliminary plan settles the questions that decide which professionals you need and what they draw. Louisiana shows how sharp that is: the State Fire Marshal's example is a 20,000 sq ft warehouse with a 5,000 sq ft office, which needs an architect, not a civil engineer, because the business portion exceeds 4,000 sq ft, and plans without a qualifying professional of record are rejected under R.S. 40:1574.1(C)(1) [3]. A plan that fixes the program, the occupancy mix and the floor areas before design starts tells you which seal the building needs.
The preliminary plan also carries the work that comes before design: testing yield, parking and density against the code, taking the layout through pre-application and concept review, giving a lender and a contractor something real to price, and deciding whether to buy the site. The site plan consultant page covers those stages with each jurisdiction's published rules, and the preliminary site plan page covers the deliverable. When the program is settled, the architect and engineer of record start from a reviewed layout instead of a blank sheet.
Site plans in Texas
Developers looking for a site plan architect in Texas start from the same preliminary plan. For an RV park, Texas county orders add layout rules: Jefferson County's regulations add a preliminary site plan stage before construction plans [53], and Parker County's infrastructure requirements set a 5.0 acre minimum and 12 ft between RVs with slide-outs extended [54]. The engineering triggers come from TCEQ: a public water system exists at "at least 15 connections or 25 people at least 60 days out of the year," an on-site system treating over 5,000 gpd needs a TCEQ domestic wastewater permit, and disturbing 1 acre or more requires Construction General Permit TXR150000 [55]. Those are the points where your engineer of record takes over from the preliminary plan.
The seal rules sit beside the plan. The Texas Architects Act exempts a private commercial building of 2 stories or less and 20,000 sq ft or less (Occ. Code 1051.606(a)(4)(D)) [7], while any building for 24-hour custodial care needs an architect regardless of size (1051.703(a)(1)) [27]. The engineering board lets preliminary engineering documents be released unsealed when marked as not for construction, bidding or permit use and carrying the firm name and registration number; the final version is sealed, signed and dated before release (22 TAC 137.33(e), (f), (n)) [56]. In San Antonio, construction documents by a registered design professional are mandatory for Group A (City Code Sec. 10-8(a)(1)) [57], so an office or retail building converted to a full-service restaurant takes a registered design professional for the permit set; the restaurant conversion case study walks that path. The state overview is on site plans in Texas.
The Texas model projects show the approval path in a real jurisdiction: the RV resort in Bandera County, the express car wash in Mansfield, the truck stop in Waller County and the RV and boat storage project in Montgomery County. The state detail is on RV park site plans in Texas, car wash site plans in Texas and RV park approval in Texas counties.
Asset classes and states
The asset hubs carry the layout standards for each class: RV parks, RV resorts, hotels, self storage, car washes, warehouses, retail centers, office and single-family and townhome. State pages set out each state's approval layers: Alaska, Arizona, Colorado, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, Montana, New York, North Carolina, Ohio, Tennessee, Utah, Virginia, Washington and Wisconsin, with the rest on service areas.

Frequently asked questions
Do I need an architect for a site plan?
For the site plan itself, it depends on the state and the jurisdiction. Iowa lets an Iowa licensed architect, professional engineer or landscape architect seal site and plot plans [6]; Illinois requires a land surveyor's seal beside the design professional's when the plan shows boundary dimensions or bearings [1]; Cedar Rapids wants a registered civil engineer to certify even the preliminary site development plan [33]. The preliminary site plan that comes first carries no seal.
When does the building need an architect?
When it crosses the state's line. Texas exempts private commercial buildings of 2 stories or less and 20,000 sq ft or less from its Architects Act [7]; Tennessee requires an architect or engineer for business, mercantile, storage and similar buildings of three stories or 5,000 sq ft gross [4]; Wisconsin lets any person make plans for a new building under 50,000 cubic feet [5]; Louisiana sets occupancy thresholds such as 4,000 sq ft for business uses on projects costing more than $125,000 [2, 3]; Alabama requires a registered architect for any building of 2,500 square feet or larger other than those exempted [11].
Can a site plan go to the city without a seal?
Where the rule says so, yes. Arizona's Board rule lets a registrant submit a document to a regulatory or review body unsealed when it is marked "preliminary," "draft" or "not for construction" (R4-30-304(D)) [39]. Missouri's statute requires no professional to seal preliminary or incomplete documents, while final technical submissions carry the seal (RSMo 327.411) [42]. Gaston County, North Carolina encourages, but does not require, a site plan prepared by a licensed professional [45].
Can an architect stamp a plan the studio drew?
Not as a finished drawing. Wisconsin bars a registrant from sealing documents not prepared by the registrant or under the registrant's direction and control [51], and Illinois holds that merely reviewing and correcting work prepared by others is not responsible control [1]. The architect of record develops the sealed set from the preliminary plan, under the architect's own control.
Who seals the boundary and the topography?
Does the studio provide architect or engineer seals?
No. The studio holds no stamp and does not do the engineering. Its preliminary site plan is the layout, the yield and the site data table that your architect and engineer of record build the sealed set on.
Why bring a preliminary site plan to the architect first?
It settles the program, the occupancy mix and the floor areas that decide which professional of record you need. In Louisiana, a 20,000 sq ft warehouse with a 5,000 sq ft office needs an architect, not a civil engineer, because the office exceeds the 4,000 sq ft business threshold [3].
